Direct Access to (±)-10-Desbromoarborescidine A from Tryptamine and Pentan-1,5-diol

A single step synthetic strategy for (±)10- Desbromoarborescidine A is described. Starting from tryptamine and pentan-1,5-diol, this acceptorless dehydrogenative condensation process is efficiently catalyzed by a ruthenium complex featuring proton-responsive phosphine pyridone ligand.
